Application filed September 28, 1914. Serial No. 863,856.

To all io/om it may concern Be it known that I, VINCENT G. APPLE, a citizen of the Unitedv States, residing at Dayton, in the county of Montgomery and u State of Ohio, have invented certain new and useful Improvements in Centrifugal peed-Governors, of which the following istv a specification. l My invention relates to improvements in centrifugal speed governors. A

One ofthe genera-l objects of my invention is to provide a governor, vwhich is responsive to slightchanges of speed, whereby to maintain substantially constant the rate of speed of a rotating shaft controlled thereby. y

Another and more specific object'bf my invention is to provide a more sensitive structure; one that is Cheaper to produce and more durable and to generally improve the shape, character and relation th parts.

Other and further objects of myinvention will become readily apparent,v to personskilled in the art, from a consideration of the following description when taken in conjunction with the drawings, wherein- Figure 1 is an end elevation of the governor. governor, looking at the opposite end. llnig. 3 is a side elevation. Fig. d is a central,

longitudinal section taken on linea-4L of4 Fig. 1. Fig. 5 is a transverse section taken on line 5-5 of F ig. ,4. Fig. 6 1s the pattern of the friction producing covering, or leather.

for the tapered surface 4of the pulley'. Fig. 7 is 'a key to hold the driven elements to the sleeve, that is to be attached to the shaft.

ln all the views the same reference characters are employed to indicate similar parts.

rllhe device contains two maj or elements, a sleeve 10 having attached thereto a disk 1l which forms one Wall for the annular chainber containing the ball Weights, and the pulley portion 12,- Which is slidableupon the sleeve. The sleeve 10 is provided with a head 14, at one end, and is screw threaded,

as at 15, at the other end. The disk 1 1,v

preferably, is provided With a sleeve portion 1G, screw7 threaded lonto the' end of tlie.

sleeve 10, and secured thereon by nut 17 and check nut 18. The disk 11 is provided near its periphery, with a laterally\obl1que surface 19, the disk becoming thicker near its periphery, theobjcet and use of Which will Specification of Letters Patent.'

Fig. 2 is an end elevation of the vPatented July 6, 1915.

be hereinafter Ymore fully explained. .Thel

pulley l2 consists of a disk portion 20, having an integral sleeve or hub which is longitudinally slidable upon the sleeve 10 and a sleeve 10 and bears against the head 14Y thereof, the effect of -the spring being t0 hold the parts in the relative positions shown in Fig. fl.

A. conical portion l22, of the pulley 12, is

` covered with a yielding, friction producing material, such as leather 27, the pattern for.

which is shown as a fragment, in Fig. 6. The leather 27 is cut in the shape of a notched disk as shown and formed up into a cup-shape such as shown inFig. l, so that it will fit neatly over the tapered conel 22. After the friction leather 2T has been pressed into' cup-shape, in a 'suitable mold .and under pressure,it is applied to the conical part 22N'of thepulley and the 'fiat ring 29 is placed'thereover and held in place by screws 30 that take into the smaller part of the cone 22 of the pulley. The peripheral wings 31 of the leather 2T are folded down over the larger edge of the conical pulley 22, as shown 1n F ig. 5, and`they are held 1nplace by the screws 23 which pass through the ldisk 22 and the leather 27 into the larger portion of the conical pulley 22. A series of balls, preferably hardened steel ball-s 32, are placed in the .chamber provided between the disks 11 and 12. ln the particular exelnplification there are nine suelr-balls, as

clearly shown in Fig. of 'A key 21 secures the disk 2O to the sleeve 10.

The operation of the governor isl as folv' lows :e-The sleeve 10 is placed on.a shaft, the speed of which is to beeontrolled and the set screws 33 are set down into the shaft so as to secure the sleeve 10 thereon. The

' surfacc'? 'is in contact therewith in order that` the governor pulley will make frictional contact with the driving pulley to rotate the shaft to be controlled. The centrifugal effect produced by the rotation of the pulley will cause the-balls 3'2 to fly out -tangentially, to a circumferential plane of rotation, at `which time they will press against the tapered lateral projectionl) of the disk ll and being in contact with the shaft tend to decrease beloiv the predeteri speed at which the shaft should be driven is mined velocity, the spring 2l vvill push the laterally movable pulley 12 again into contact with the driving pulley. The rate at which the governor shaft Will be rotated under a given speed of the driving element is determined by the relation of the balls 32 and the spring 24.

' In lthe present exemplilieation there is no i means present for adjusting the effect ofthe spring 24:, but such means could be easily applied if desired. In many devices the determined in the factory and it is highly desirable that that rate shall not be changed when the device is in the hands of an inexperienced user and for that cause alone the absence -of means for adjusting the relation of the centrifugally responsive balls and the spring is desirable` llf'hile I have herein shown and described a single embodiment of my invention for the purpose of clear disclosure it is manifest that changes may'bemade in the form and relation of the parts Within the scope of the appended claims.

Having described my invention, what I claim is I l. A self contained, speed responsivegovernor, comprising a sleeve; a disk secured thereto; another disk spaced apart from the first disk axially movable on said sleeve, but rotatable therewith, one or bot-h said disks having confronting, laterally projecting, circumferentially contiguous tapered surfaces, approaching each other near their peripher T; a pulley part, secured to the latter disk and closing the annular space bctWeen said disks; a spring tending to yieldingly hold said disks together and a series of balls Within said annular space.

2. A self contained, speed responsive governor, comprising a sleeve: a disk secured thereto; another disk spaced apart from the fixed disk, axially movable on said sleeve but rotatable therewith, one or both said disks having confronting, laterally projecting.

circumferentially contiguous` tapered sur-- faces; a pulley part; having a tapered fric tional driving surface, secured to the latter' disk and closing the annular space between said disks; a spring conn)risingv a. arranged series of lingers bearing on the axially movable disk near its periphery, perforated near its center' and overlying said sleeve, tending to yieldingly hold said disks together and a series of balls within said annular space.

3. speed responsive governor, comprising a part laterally fixed; a driving pulley part, laterally movable with respect to the fixed part; and centrifugally responsive. means positioned vvithin the axial contines of said pulley part for laterally separating said parts.

i, A speed responsive governor comprising a part laterally lixed; a driving pulley part laterally movable with respect to the fixed part and spaced aparttherefrom to lprovide an annular chamber; centritugally A pulley adapted to be frictionally driven and moved into or out of engagement with its driving member by means of speed responsive "mechanism, comprising a base member, rings adapted to be clamped against each end thereof, and a covering composed of a disk of leather secured near its center to one end of the pulley by one of said rings and similarly secured at its periphery to the other end of the pulley.

G. A pulley adapted to be frictionally driven, comprising a base member, a covering comprising a disk of leather and means for securing the same near its center and periphery to opposite ends of the base member.

In testimony whereof I hereunto set my hand in the presence of two subscribing witnesses. l l
